铝和铝合金的阳极氧化.阳极氧化涂层耐磨性测量

[中文适用范围]： 本文件规定了以下试验： a) 砂轮磨损试验，测定铝及其合金平面试样上砂轮阳极氧化涂层的耐磨性； c) 落砂磨损试验，用落砂测定铝及其合金阳极氧化涂层的耐磨性。 b) 磨料喷射试验，用磨粒喷射在铝及其合金阳极氧化涂层上测定阳极氧化涂层的耐磨性比较； ISO 10074 中描述了对硬质阳极氧化涂层使用磨料轮磨损测试和磨料喷射测试的方法。 [外文原描述]： This document specifies the following tests: a) abrasive-wheel-wear test, determining the abrasion resistance of anodic oxidation coatings with abrasive wheel on flat specimens of aluminium and its alloys; b) abrasive jet test, determining the comparative abrasion resistance of anodic oxidation coatings with jet of abrasive particles on anodic oxidation coatings of aluminium and its alloys; c) falling sand abrasion test, determining the abrasion resistance of anodic oxidation coatings with falling sand on thin anodic oxidation coatings of aluminium and its alloys. The use of abrasive-wheel-wear test and abrasive jet test for coatings produced by hard anodizing is described in ISO 10074.
